Highest temperature in Singapore on August 6?

Platform comparison

Market context

Polymarket prices this Singapore high-temperature contract at 0% YES, which implies the crowd is effectively assigning no odds to the listed resolution band as the day unfolds. Settlement is tied to the highest reading at Singapore Changi Airport Station on Wunderground, with outcomes paid in USDC via Polygon conditional tokens, so the practical question for traders is whether the day’s eventual peak lands in the market’s eligible Celsius bucket before the resolution window closes.

For context, Singapore’s August climate is usually hot and humid, with model-based monthly highs clustering around the low 30s Celsius rather than the mid-30s. AccuWeather’s August outlook shows daily highs mostly between 84°F and 88°F, while climate summaries from WeatherSpark put typical August daily highs around 88°F, or roughly 31°C, with very little day-to-day variation.[1][20] NEA’s fortnight advisory also points to fair, occasionally windy conditions and daily maximums of 33°C to 34°C on most days, which matters because a brief shower or cloud build-up can keep the station’s top reading from reaching the upper end of the range.[12]

A trader should watch the morning and early-afternoon forecast updates, especially any thundery-shower wording for the Singapore area, because localised rain can clip the intraday maximum even when the broader forecast stays hot.[12] The market’s reference point is Changi Airport Station rather than city-centre feel or regional averages, so the decisive catalyst is the official hourly temperature path on Wunderground during Singapore time, not the headline weather elsewhere in the island.[11]
